Resizing for Canvas
Any field in the PI that corresponds to a DOM attribute such as:
Element Id
All image and Video properties
Custom component properties
Any edit that adds or deletes elements. For example, using the tag, canvas, or text tools; drag-and-dropping an asset or component on stage; deleting, cutting, or pasting the current selection; and creating a group, breaking apart an instance, or wrapping/unwrapping.
Any edit involving events or dynamic data binding
To hide/Show content when a particular media rule is active, in Properties panel select Visibility : Visible
The visibility property sets or returns whether an element should be visible.
I hope this helps.
Thanks
